The item was easy to pair and provided great information. For me, it was uncomfortable to wear and made it a bit difficult to do daily tasks. While I am more tempted to wear a ring more constantly than a watch, this is a bit uncomfortable.

Overall, this ring is a great concept. I just don't think the technology is there yet. It's an awesome concept, but the battery does not hold charge for more than a day after using this smart ring for three months. It does not want to connect and I do not believe it's very accurate in the sleep tracking or steps. It also left a white ring around my finger and not just a tan line.
